Solution:
Option(B) is correct

Input: 544 (13), 653 (14), 325 (10), 688 (22), 461 (11), 231 (6), 857 (20).

Step 1: 231 (6), 653 (14), 325 (10), 688 (22), 461 (11), 544 (13), 857 (20).

Step 2: 231 (6), 325 (10), 653 (14), 688 (22), 461 (11), 544 (13), 857 (20).

Step 3: 231 (6), 325 (10), 461 (11), 688 (22), 653 (14), 544 (13), 857 (20).

Step 4: 231 (6), 325 (10), 461 (11), 544 (13), 653 (14), 688 (22), 857 (20).

Step 5: 231 (6), 325 (10), 461 (11), 544 (13), 653 (14), 857 (20), 688 (22).

$\therefore$ Total 5 steps would be required.

Hence, option B is the correct choice.
